IMPROVEMENT IN SAFETV-PINS.

Specification forming part of Letters Patent No. 126,811, dated May 14,1872.

To all whom it may concern:

Be it known that I, ROBERT W. HUsroN, of the city of Washington,District of Columbia, have invented a new and useful Safety-Pin; and Ido hereby declare 'that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawingmaking part of this specification, in which- Figure l is a view of thesafety-pin inserted into a piece of cloth, as it might appear when usedas an attachment for the chain of a watch to some part of a vest. Fig. 2is a view of the pin enlarged, and detached from a piece of cloth.

Similar letters of reference indicate corresponding parts in the twogures. v

The object of this invention is to obtain a safety-pin, which, when itis inserted into cloth, cannot be removed without unserewin g ortwisting it backward one or more turns, as will be hereinafterexplained.

The following explanation willy enable others skilled in the art tounderstand my invention.

In the accompanying drawing, c represents the stem of the pin, which ispointed on one end, and which terminates at its opposite end in a loopedhead, ct. This head is adapted to receive the lilik of a chain, or ahook or head or end of a pin or nail. It is either oblong' or circular,and the wire which forms it is bent around the stem o in the form of ahelix, b, having one or more coils terminating in apenetrating point, c.

It will be seen that my improved pin con sists of a simple wire, ofsteel or other metal, which is point-ed at both ends, one end beinglooped and coiled, as shown in the drawing. A pin thus formed affords ameans of attachment for a watch-chain to a vest 5 also a means ofattachment for the chain of a shirt-stud to a shirt; and it may also beused for securing down carpets to hooks or nails, and for many otherpurposes.

I am aware that a-hair-pin has been made with a spiral holding portion;but in such pin it never was contemplated that the spiral holdingportion or the straight portion should have.

a capability of penetrating cloth or any other object, for if thus madeit would be liable to injure the skin of the head of the wearer or userof such pin. While, therefore, I do not claim the invention shown in thepatent of J.

C. Howell, of August 23, 1864- Having described my invention, what I doclaim is 1. A pointed stem or shank,- c, terminating at one end in asharp penetrating pointed coil, b, substantially as described.

2. The loop a, combined with a sharp penetrating pointed coil b, and apointed stem, c, substantially as described.
